How did your consultations go with the above mentioned doctors?
I believe that this will help you decide. When you consult with a clinic, you will see just how much time and effort they put towards you.
Will the doctor even speak to you, or will you only talk to sales reps? Do they rush you? Do they pressure you? Do they listen to you? Are they prompt and professional in coresspondences?
Lorenzo is right, it's not a popularity contest. But if a doctor isn't willing to give you the time of day and assurances you need pre-op, then just imagine how you will be treated post-op when things can get a little worrisome.
